Application filed May 20, 1914. Serial No. 839,874.

T0 all 'whom it may concern:

Be it known that I, ARTHUR W. BUTTER- FIELD, a citizen of thek UnitedStates, and resident of St. Louis, Missouri, have invented certain newand useful lmprovements in Oil-Vaporizers, of which the fol-- lowing isa specification containing a full, clear, and exact description,reference being had to the accompanyingv drawings, forming a parthereof.

My invention relates to improvements in oil vaporizers, in which afinely divided balile is interposed between the source of oil supply anda steam line to atomize the oil in live steam before its entry into thesteam line, and the object of my improvements is to inject into thesteam line a stream of steam thoroughly impregnated with the minutestatoms of lubricant which will commingle with the steam in the steam lineand be carried thereby to the remotest parts of the engine or othermachinery subjected to said steam resulting in increased efliciency ofthe engine or other machinery and a saving in lubricant. I attain thisobject by an employment of the device hereinafter fully set forth in myspecication, pointed out in my claims and illustrated by theaccompanying drawings, in which- Figure 1 shows my device as in usebetween a sight feed lubricator and a steam line; Fig. 2 is a verticalsectional elevation of the device of my invention detached from thesight feed lubricator and steam line; and Fig. 3 is a detail perspectiveof my preferred form of baiiie.

In this application have elected to show and describe my improved oilvaporizer in connection with a sight, up-feed lubricator, but do notwish to be understood as limiting myself to the use of my device inconnection with this form of lubricator alone, as any other form ofmeans for supplying lubricant to my improved atomizer in controlledquantities may be advantageously employed.

Referring by numerals to the accompanying drawings: 4 designates the oilreservoir of an ordinary sight, up-feed 7 lubricator. To one side of thereservoir is located an indicator glass 5, and on the other side of thereservoir is a sight feed glass 6. At the lower end of the sight feedglass there is a valve 7 for regulating the flow of oil from thereservoir through the sight feed glass. Extending laterally from theupper end of the reservoir and in communication with the upper end ofthe Vsight feed glass is a discharge valve 8.

9 designates a steam pipe, or a steam line which is arranged forconnection with a source of steam supply and with a steam engine orother machinery requiring lubricated steam for its operation.

10 designates a condenser pipe leading from the steam line 9 to thedischarge valve of the lubricator, and located in this condenser-pipe isa valve 11, whereby the steam may be cut o when it is desired to openthe oil reservoir for purposes of filling or repair.

12 designates the body portion or casing of my atomizer, which isprovided at its upper end with an internally threaded eX- tension 13arranged for connection with the discharge valve 8 of the lubricator.Within the casing 12 below the point of connection with the dischargevalve of the lubricator is a centrally perforated, horizontal wall 14and in the upper end of the casing alining with the opening in thehorizontal wall is an internally threaded boss 15, which provides meansfor connecting the atomizer with a live steam pipe, such as 16, which ispreferably tapped into the condenser pipe 10 and provided with a valve,such as 17, for controlling the steam to the atomizer. `Within thecasing beneath the horizontal wall 14 is a shoulder 18, and restingagainst this shoulder is a baffle plate 19, whose uppermost face isconveXed and which is provided with a plurality of radially arrangedslots at or near its periphery.

20 designates a second baiile plate, which is connected integrally withthe plate 19 by a stem 21, whose uppermost face is conveXed and throughwhich plate there is formed a plurality of minute openings 22.

The lowermost end of the casing is internally threaded to receive a head23 and projecting upwardly from this head is a number of lingers 211arranged for the support of the baffle plates 19 and 20. Formed on thebottom of the head 23 is a boss 25, having a threaded bore, and which isnoncircular, externally, to provide for fully seating the head by meansof a wrench.

26 designates a pipe, including an elbow, which forms a communicationbetween the atomizer and the steam line.

The practical operation of my improved atomizer is as follows: Assumingthe lubricator to be connected up as shown and periodically ejectingdrops 7 of oil in a common manner, it is to be understood that thesedrops Will be carried by pressure from the condenser pipe, and bedeposited on the Wall 14 of my atomizer, from Which the sirens will findthe Opening in Said Wall and be carried therethrough by live steam fromthe pipe 16 to the baiiie plate 19. By reason of the high temperature ofthis plate 19, due to its being located in the path of live steam, theoil Will be thinned and be in better condition for comminution inpassing through the slots in the plate 19 under the pressure of thesteam. The steam and comminuted lubricant after having passed throughthe baffle 19 are then forced through the minute openings in the secondbaie Which thoroughly impregnates all of the steam With the minutestatoms of lubricant, and in this condition the lubricant is delivered tothe steam line Where it Will be carried to the remotest parts of theengine or other machinery.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters Patent of the United States therefor, is z'l. In a device of the class described, a casing, separate and distinctmeans adjacent one end of the casing for connecting the casing With asource of oil supply and With a source of live steam supply, a fixedWall Within Mthe casing having a perforation therein in the joint pathsof oil and steam, a baiiie, Within the casing adjacent the perforatedWall, having minute openings therethrough out of the direct path ofsteam and oil discharged through the opening in said Wall, said casinghaving an outlet common to the 'steam and oil on the side of the baHeopposite the perforated Wall.

2. In a device of the class described, a casing having at or adjacentone end a steam inlet and an oil inlet, a iixed Wall beneath said inletsand having a perforation therethrough, a baiiie having a convenedsurface imperforate in the direct path of steam and oil dischargedthrough said perforation, but having minute perforations out of saidpath of steam and oil, a second baiiie spaced from the first mentionedbaille, means for detachably holding the baiiles in place within thecasing and said casing having an outlet common to the steam and oil,

substantially as shown and for the purposes i stated.

ln testimony whereof, l have signed my name to this specification, inpresence of two subscribing Witnesses.
